VEHICLE SPRING CONNECTION.

Specification of Letters Patent.

Patented June i), 1914.

Application led March 3, 1914. Serial No. 822,177.

To all whom tt may concern a citizen of the United States of America, residing at Pontiac, in the county of Oakland and State of Michigan, have invented certain new and useful Improvements in Vehicle Spr-ing Connections, of which the following is a specication, reference being had therein to the accompanying drawings.

The invention. relates to4 vehicle springs, and more particularly to the connecting means betweencthe spring and vehicle frame. It is the object of the invention to obtain a construction in which adjustment may be readily made to take up wear and prevent rattling, as hereinafter set forth.

In the drawings: Figure 1 is a sectional elevation of a vehicle spring supporting shackle and bracket; Fig. 2 is a similar view showing a bracket without the shackle.

In the present state of the art, vehicle springs, suchl as elliptic, semi-elliptic and leaf spring constructions, are usually attached to the frame through pivotal connections to brackets or shackles. The constant vibration or oscillation of the parts,v when the vehicle is in motion will producewear which in `a short time results in rattling. With my improved construction, provision is made for easily taking up any wear, so as to prevent this rattling.

In detail, A is a bracket attached to the frame; B is a shackle pivotally'connected to the bracket and at its opposite end pivotally connected to the spring Grand D are bolts or pins forming the pivotal con- -nections and which nass through alined eyes "E and F respectively in the shackle and bracket or spring. The shackle B is bifurcated to embrace the eyes F, and as the separated arms or urcations are a Xed dis j 'i tance apart'theywcannot be adjusted to take up lateral wears-,Lhave, however, made provision fifgr this .lateral adjustment by placing a sleeve Gr upon the bolt D adjacent to the head H thereof, forming on thec inner end of this sleeve a head I which bears against the bracket. The opposite end oi the bolt D isthreaded at J to engagea correspondingly threaded bearing in the arm of the shackle, and a lock nut K is'employed to hold the parts in any desired position of adjustment. In use, Whenever the parts wear so as to pro duce play between the sleeve G and the eye F on the bracket, this lost motion may be taken up by loosening the lock nut K and thenturning the head II of the bolt. so as to` secure the same into the threaded bearing in the shackle. This will carry the bushing G and head I thereof with the bolt and will take up the lost\motion. A similar adjustment may be made between the shackle and spring.

In Fig. 2 a similar construction is shown, but one in which the eye of the spring is directly attached to thebracket without the medium of the shackle. Wit-h this construction the placing oli the lock nut upon the opposite end of the bolt from the head would not be a convenient location for adjustment, and I have therefore substituted ,a locking device L, which directly engages the hexagonal head H of thebolt.

What I claim as my invention is:

1. A pivotal connection for iehicle springs, comprising a bifurcated bearing embracing the same'and apertured in alinement therewith, a pivot pin passing through the alined bearings, a sleeve upon said pin engaging the aperture in one of the furcations and extending between opposed shoulders on said pin head on said pin forming a shoulder in con' tact with the-opposite end of said sleeve.

3. A pivotal connection for vehicle springs, comprisin an apertured bearing, a bifurcated bearing embracing the same and-"apertured in alinement therewith, a pin passing through said alined apertures having a threaded end engaging one of the furcations, a. sleeve upon said pin engaging the aperture in ,the opposite furcation, its inner 'end being in contact with the end of the embraced bear-ing, a head on said pin contacting with the opposite end of said sleeve, and means torlocking said pin indilierent positions of adjustment of its threaded portion with the thiladed furcation.

4. A pivotal connection for vehicle springs,

comprising an apertured bearing, a bifurder for the opposite end of said sleeve, and
